Heat-radiating device assembly

Abstract

A heat-radiating device assembly includes at least a radiator including a base, a plurality of radiating fins, and two heat pipes. The radiating fins are aligned in parallel on the top surface of the base and two opposite and large area radiating surfaces are provided thereon, each of the upper side of the radiating surfaces is provided with two through holes. The two heat pipes are connected and mounted between the through holes of the radiating fins and the base, the lower surface of the base is attached with the top surface of an electronic element to radiate heat therefrom, wherein one lateral edge of the radiating surfaces of the radiating fins is generally arc shaped, V-shaped in the disclosed embodiment, with two raised outward upper and lower ends and a depressed inward center. With the structure of the radiating fins shown in the present invention, the windage of the radiator is reduced and the amount of air flow is increased, and thus the reduced noise and the improved heat dissipating effects are obtained. In addition, the radiating fin structure used in the present invention reduces the material used to make the radiating fins thereby reducing the weight.
